Recommended Uses

EP HiBuild Primer is intended for industrial applications; either new build or maintenance. EP HiBuild Primer is suitable for application on steel, aluminum, stainless steel, fiberglass, other ferrous metals and fiberglass reinforced plastics. This primer must be topcoated to achieve the best results.

Industrial Applications:

  • Offshore Drilling Rigs
  • Pulp Mills
  • Chemical Plants
  • Boats
  • Bridges
  • Marine

This primer is not suitable for automotive applications.

Mix Ratio
  • 4 part by volume of component A
  • 1 part by volume of component B

The recommended temperature when mixed is 68-77°F (20-25°C).

Surface Preparation

Surface must be free of all contaminants such as dust, oil, grease and salt. It is recommended that all steel and other ferrous surfaces be sandblasted a minimum of SSPC-SP6 or mechanically sanded with 40 grit sandpaper.

Note: For use on fiberglass or wood boat hulls, machine sand with 80 grit sandpaper. A minimum of 10 mils (250 microns) dry film thickness is required for waterproofing. Endura EX-2C Topcoat is not recommended below the waterline.

Application Method

EP HiBuild Primer can be applied using most spray systems, although electrostatic sprayers are not recommended. Apply 2-3 coats as required to achieve the desired film thickness. Allow sufficient flash time between coats especially with higher film builds applied (20-30minutes).

Spray Viscosity

Polyglass Coatings EP HiBuild Primer - Spray Viscosity


Note: Spraying viscosity and thinning will depend on ambient conditions, spray equipment used, and the desired surface finish.

If required, recommended spraying viscosity is achieved by reducing with one of the following Endura Low VOC Epoxy reducers. These will maintain VOC compliance of EP HiBuild Primer.

VOC content of the following Reducers: (0g/l, 0 lbs/gal)

[FTH0016] Low VOC Epoxy Reducer- Regular

[FTH0027] Low VOC Epoxy Reducer- Slow

Film Build

EP HiBuild Primer has a recommended film build thickness of:

WFT (Unreduced) 5.5 - 8.0 mils

140 - 203 microns

DFT 4 - 6 mils

102 - 152 microns

 

WFT (Unreduced) 13.6 mils +

345 microns

DFT 10 mils +

254 microns

The recommended dry film thickness is above the blast/sanding profile.

Theoretical coverage at 1.0 mil (25 microns)

DFT: 1173 ft² per gallon at 100% transfer efficiency. 

Dry Times
Top Coat 20°C 30°C 40°C
4 mils 3 Hours 2 Hours 1 Hours
8 mils 6 Hours 4 Hours 2 Hours
12 mils 12 Hours 8 Hours 4 Hours
Full Cure 7 - 9 Days 5 - 6 Days 3 - 4 Days

 

 

Note: Dry Times are subject to ambient conditions (temperature and humidity), good airflow and film build of primer. For best results surface temperature must be 86°F (30°C) or less before top coating. Maximum re-coat window without sanding is 24 hours at 68°F (20°C) Recommended Sanding 180 - 220 grit after the topcoat window has been exceeded. 

Top Coating Infomation

EP HiBuild Primer can be topcoated with the entire range of Endura topcoat products.

Clean Up

Clean all equipment immediately after use with Endura High Strength Gun Wash, Endura epoxy reducer or Endura EX-2C thinner.

Safety & Health

Environmental Conditions

For optimum coating performance, product, substrate and ambient temperature should be between 68°F-77°F (20°C-25°C). To prevent condensation during application the surface temperature must be 5°F (3°C) or more above the dew point at all times.
